IMPROVEMENT IN CARDING-ENGINES FOR MAKING BATS FOR FELTED FABRICS.

Specification forming part of Letters Patent No. 155,503, dated September 29, 1874; application iled i May l5, 1874.

To all whom it may concern:

-Be it known that we, HENRY J. DAVIES and WALTER D. DAVIES, both4 of Brooklyn, in the county of Kings and State of New York, have jointly invented certain Improvements in Garding-Engines for making Bats for Felted Fabrics, ot' which the following is a specification:

This invention relates to the manufacture of felted fabrics in a sheet o r web of arc form -that is, of concentric curvatureits edges presenting arcs of different radius, such web not heilig' united at its ends as it is delivered from the cardin g-en gine, and bein g especially suitable for making skirts by formin g the web of a width equal to the desired length ofthe skirt, and then cutting said web transversely into a suitable length for the circumference of the skirt, which will be of larger measurement at its bottom than at its top, and afterward uniting the ends of such'web by a single seam to produce the skirt.

This fabric we propose to make the subject of a separate application for Letters Patent, and design to include making said web with its portion toward the arc of greater circumference of a different quality of wool or stock to fthe portion which is toward the arc of lesser radius; also, -if desired, of different color, and whereby a superior and cheaper skirt may be produced, as will be described in our subsequent application for patent on the fabric. I

This invention consists in a carding-engine of peculiar construction, by which such a fabric may be produced, and which includes a feeding-apron of varying length and traveling around conical rollers, the axes of which converge to a common center; correspondingly conical or tapering feed-rollers at the -delivery end of the apron; a carding-cylinder of be a delivery apron of varying length, and traveling around rollers of fsimilar taper with that of the dofler.

In the accompanying drawing, Figure l represents a plan of a carding-engine constructed in accordance with our invention, or of such parts thereof as are necessary to illustrate the invention, all gearing being omit-4 ted. Fig. 2 is a vertical section of the same on the line :c .90..

Ais the feeding-apron, onto which the wool or stock is laid to conduct it to the cardingcylinder, said apron being of varyin g length and traveling around conical rollers B B, the axes of which converge to a common center. C C are similarly-tapering feed-rollers, arranged at the delivery end of the receivingapron, and having their inner sides parallel with the carding-cylinder, the same serving to conduct the wooloi1 bat, preferably through the interposition of the usual distributingroller or receiver, to the carding-cylinder D,

' which is of uniform diameter, or thereabout,

around rollers I I of si milarly-taperin g arrangement as the doffer.

J is the doffer-comb or stripper.

We claim- 1. The feeding-apron A, of varying length, and its conical rollers B B, in combination with the carding-cylinder D, substantially as specified.

, 2. The conical doffer G,in combination with the carding-cylinder, essentially as described.

3. The delivery-apron H, of varying length, and its conical rollers I I, in combination with the conical doffer and the carding-cylinder, substantially-as herein set forth.
